Subject: [PATCH 2/2] dt-bindings: arm: sti: add sti boards and remove stih415/stih416

Add bindings for STi platform boards and remove stih415/stih416 items.
This commit also moves the sti.yaml binding file within the arm/sti/
folder instead of arm/

Thank you for your patch. There is something to discuss/improve. Few nits.

Use imperative.

Drop "entries", does not look related to hardware.

Generic node names, thus usually syscon or system-controller

Ah, and one more - incorrect directory. This should be in soc, not arm.

Dual-license. I don't think there is anything from old binding being
copied here (you can as well start from scratch from other binding and
result will be the same).

Ok, changed to syscfg_sbc: syscon@9620000

I also move the file within bindings/soc/sti as mentioned in your other
reply.

Ok

I understand, based on your review of the other patch in the serie that
I should put this sti.yaml within bindings/soc/sti right ?

Moreover, I made a mistake and removed st,stih415 and st,stih416 in
this patch while I already posted the patch in the STiH415/STiH416
removal serie (https://lore.kernel.org/all/[email protected]/).
I propose to get rid of the patch in the other serie and do the removal
within this patch since it also moves the file.
